-We generally use upper case for constants that are "hard-coded". Or, in other words, when the value is known prior to execution and directly written into the code.
+Du skal generelt bruge uppercase til konstanter der er "hard-coded". Eller, sagt med andre ord, hvis du ved hvad værdien er når du skriver den og ikke når koden afvikles.
 
-In this code, `birthday` is exactly like that. So we could use the upper case for it.
+I denne kode er `birthday` præcist sådan en værdi, så her vil du bruge bar store bogstaver.
 
-In contrast, `age` is evaluated in run-time. Today we have one age, a year after we'll have another one. It is constant in a sense that it does not change through the code execution. But it is a bit "less of a constant" than `birthday`: it is calculated, so we should keep the lower case for it.
+Derimod vil `age` blive evalueret når koden afvikles. Idag vil du have én alder og næste år en anden. Den er en konstant i den forstand, at den ikke ændrer sig i det tidsrum koden afvikles. Men den er "lidt mindre konstant" end `birthday`. Da den er beregnet, vil du normalt skrive den i lowercase.
